Recursive regex matching in JavaScript. Official Regex+ plugin. - slevithan/regex-recursion

Currently, Oniguruma sometimes applies Unicode's SpecialCasing.txt rules when using flag i, which can lengthen the match of a character, character class, or set (like \w or \S). For example, (?i)^ß...

Convert patterns from Oniguruma (the regex engine used by Ruby, TextMate grammars, etc.) to native JavaScript RegExp - slevithan/oniguruma-to-es

TextMate grammars used for syntax highlighting can individually contain thousands of regexes and are, collectively, quite large. Their regexes can be optimized via minification that also improves t...

Closes #125. Introduces a fancy Oniguruma regex optimizer that not only minifies more robustly (e.g., C++ drops more than 35,000 characters compared to the existing minification), but also improves...

This project (oniguruma-to-es) and it's high complexity demonstrates that accurately/comprehensively converting between any two regex flavors is a hard task, and not for the faint of heart. (Though...

A common misconception about regular expression performance is that lazy quantifiers (also called non-greedy, reluctant, minimal, or ungreedy) are faster than their greedy equivalents. That's generall...

Shiki's JS engine uses Oniguruma-To-ES under the hood to emulate Oniguruma regexes. As of the latest version, the vast majority of grammars (which contain dozens to thousands of regexes each) are s...

Although JavaScript regexes used to be underpowered compared to other modern flavors, numerous improvements in recent years mean that’s no longer true. Steven Levithan evaluates the history and presen...
